@guga You certainly have your plate full, don't you? I hope your doctor has considered referring you to a rheumatologist for the arthritis, and I am wondering if physical therapy would help at all? Gentle yoga and stretching seems to help, as well. Good for you for pushing yourself a little bit more each day! Like @mamacita said, keeping a journal of the pain, or making a chart of your symptoms, will be of use to both you and your doctors.
